Technical Field

[0001] This utility model relates to the field of steel slag asphalt technology, specifically to a steel slag asphalt pavement mixing and stirring device. Background Technology

[0002] Steel slag asphalt is a road paving material made by mixing steel slag as the main aggregate with asphalt binder. It is a typical application of recycled aggregate asphalt mixture. Its core value lies in resource recycling and performance optimization, transforming industrial waste into road materials and improving the rutting resistance and wear resistance of asphalt pavement.

[0003] Based on the above, the following problems were found: When mixing steel slag asphalt, the current mixing equipment is prone to problems such as the high density of steel slag causing separation and uneven mixing with asphalt, which will affect the pavement strength and make it inconvenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a steel slag asphalt pavement mixing device to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a uniform mixing device for steel slag asphalt pavement to solve the problems mentioned in the background art.

[0006] A uniform mixing device for steel slag asphalt pavement includes a mixing component, which contains a stirring component. The mixing component includes a stirring chamber, and the stirring component includes a spiral scraper. The spiral scraper is disposed inside the stirring chamber and is rotatably connected to the stirring chamber. The spiral scraper is in contact with the inner bottom of the stirring chamber. A stirring shaft is rotatably connected to the inner side of the spiral scraper. Several stirring paddles are fixedly installed on the outer side of the stirring shaft. The stirring shaft and the spiral scraper rotate coaxially but in opposite directions. The stirring paddles and the spiral scraper have the same spiral twisting direction.

[0007] By adopting the above technical solution, the mixing chamber provides a convenient main mixing space to accommodate the mixing components and steel slag asphalt, facilitating the mixing of the steel slag asphalt. The spiral scraper allows for easy rotation within the mixing chamber, mixing the steel slag asphalt and continuously scraping the bottom steel slag to suspend it and prevent sedimentation and stratification. The mixing shaft provides a mounting base for the mixing paddle, allowing it to rotate within the spiral scraper. The helical twisting direction of the mixing paddle and the spiral scraper is the same, facilitating the rotation of the mixing shaft to drive the mixing paddle to rotate in the middle of the mixing chamber for mixing. Furthermore, the coaxial but opposite rotation of the mixing paddle and the spiral scraper creates opposing vortices within the mixing chamber, enhancing mixing and preventing stratification.

[0008] Furthermore, an insulation sleeve is fixedly installed on the outside of the stirring chamber, and an electric heating wire is fixedly installed between the insulation sleeve and the stirring chamber.

[0009] By adopting the above technical solution, the setting of the insulation sleeve and electric heating wire facilitates the electric heating wire to provide a heat source to heat the inside of the mixing chamber, so as to keep the steel slag asphalt fluid. The insulation sleeve provides insulation to the outside of the mixing chamber, reduces temperature loss, and avoids uneven temperature.

[0010] Furthermore, the bottom of the mixing chamber is connected to a discharge port, and a control valve is fixedly installed in the middle of the discharge port.

[0011] By adopting the above technical solution, the discharge port is designed to facilitate the discharge of the well-mixed steel slag asphalt, and the control valve controls the opening and closing of the discharge port.

[0012] Furthermore, a top cover is hinged to one end of the insulation sleeve, and a gear cavity is fixedly installed on the outer side of one end of the insulation sleeve.

[0013] By adopting the above technical solution, the top cover and gear cavity are designed to facilitate the opening of the top cover to add materials into the mixing chamber for mixing. The gear cavity is used to protect each gear and to provide a mounting base for the drive motor.

[0014] Furthermore, the hybrid assembly also includes a drive motor, which is fixedly mounted on top of the gear cavity.

[0015] By adopting the above technical solution and setting the drive motor, it is easy to provide power to drive the stirring shaft and spiral scraper to rotate.

[0016] Furthermore, a worm gear is fixedly installed at the output end of the drive motor, the worm gear is meshed with a worm wheel, and the worm wheel is fixedly connected to the stirring shaft.

[0017] By adopting the above technical solution, the worm gear is designed to facilitate the operation of the drive motor, which in turn drives the worm to rotate, thereby controlling the rotation of the stirring shaft.

[0018] Furthermore, a drive gear is fixedly installed at one end of the stirring shaft where the worm gear is located, and the drive gear is meshed with a first transmission gear.

[0019] By adopting the above technical solution, the setting of the drive gear facilitates the rotation of the stirring shaft, which in turn causes the drive gear to drive the first transmission gear to rotate in the opposite direction.

[0020] Furthermore, a second transmission gear is fixedly installed on the middle of one side of the first transmission gear, and the second transmission gear is meshed with a third transmission gear. Both the first transmission gear and the third transmission gear are rotatably connected to the inside of the gear cavity.

[0021] By adopting the above technical solution, the setting of the second transmission gear facilitates the reverse rotation of the first transmission gear to drive the forward rotation of the third transmission gear.

[0022] Furthermore, the third transmission gear is meshed with a driven gear, and the driven gear is fixedly connected to the spiral scraper.

[0023] By adopting the above technical solution, the driven gear is set so that the forward rotation of the third transmission gear can drive the driven gear to rotate in the opposite direction, thereby controlling the spiral scraper to rotate in the same direction but in opposite directions. It can also reduce speed, so that the spiral scraper rotates at a slower speed, thereby outputting greater torque to scrape the bottom inside the mixing chamber. It can also reduce the wear rate of the spiral scraper and help to improve its service life.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows: The mixing chamber provides a convenient main mixing space to accommodate the mixing components and steel slag asphalt, facilitating the mixing of the steel slag asphalt. The spiral scraper allows for easy rotation within the mixing chamber, mixing the steel slag asphalt and continuously scraping the bottom steel slag to suspend it and prevent sedimentation and stratification. The mixing shaft provides a mounting base for the mixing paddle, allowing it to rotate within the spiral scraper. The fact that the mixing paddle and spiral scraper rotate in the same spiral direction allows the mixing shaft to rotate the mixing paddle in the center of the mixing chamber for mixing. Furthermore, the coaxial but opposite rotation of the mixing paddle and spiral scraper creates opposing vortices within the mixing chamber, enhancing mixing and preventing stratification. This utility model enables the spiral scraper and mixing paddle to rotate coaxially but oppositely within the mixing chamber, effectively mixing the steel slag asphalt and preventing sedimentation and stratification, thus possessing high practical value.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model provides a technical solution: a uniform mixing device for steel slag asphalt pavement, including a mixing component 1, with a mixing component 2 inside the mixing component 1. The mixing component 1 includes a mixing chamber 11, which provides the main mixing space to accommodate the mixing component 2 and the steel slag asphalt, facilitating the mixing component 2 to mix the steel slag asphalt. The mixing component 2 includes a spiral scraper 21, which is disposed inside the mixing chamber 11 and rotatably connected to the mixing chamber 11. The spiral scraper 21 is in contact with the inner bottom of the mixing chamber 11, allowing it to rotate within the mixing chamber 11 to mix the steel slag asphalt and continuously scrape away the bottom steel slag. To suspend the asphalt and prevent sedimentation and stratification, a stirring shaft 22 is rotatably connected to the inner side of the spiral scraper 21, and several stirring paddles 23 are fixedly installed on the outer side of the stirring shaft 22. The setting of the stirring shaft 22 facilitates the installation of the stirring paddles 23, allowing the stirring paddles 23 to rotate inside the spiral scraper 21. The stirring shaft 22 and the spiral scraper 21 rotate coaxially but in opposite directions, and the stirring paddles 23 and the spiral scraper 21 have the same spiral twisting direction. Because the stirring paddles 23 and the spiral scraper 21 have the same spiral twisting direction, the rotation of the stirring shaft 22 facilitates the rotation of the stirring paddles 23 in the middle of the mixing chamber 11 for mixing. The coaxial but opposite rotation of the stirring paddles 23 and the spiral scraper 21 causes the steel slag asphalt inside the mixing chamber 11 to form a counter-current vortex, enhancing mixing and preventing stratification.

[0029] An insulation sleeve 12 is fixedly installed on the outside of the mixing chamber 11, and an electric heating wire is fixedly installed between the insulation sleeve 12 and the mixing chamber 11. The insulation sleeve 12 and the electric heating wire facilitate the electric heating wire to provide a heat source to heat the inside of the mixing chamber 11, so that the steel slag asphalt maintains its fluidity. The insulation sleeve 12 provides insulation for the outside of the mixing chamber 11, reducing temperature loss and avoiding uneven temperature.

[0030] The bottom of the mixing chamber 11 is connected to a discharge port 13, and a control valve 14 is fixedly installed in the middle of the discharge port 13. The discharge port 13 facilitates the discharge of the evenly mixed steel slag asphalt, and the control valve 14 controls the opening and closing of the discharge port 13.

[0031] The top of the insulation sleeve 12 is hinged to a top cover 15, and a gear cavity 16 is fixedly installed on the outer side of one end of the insulation sleeve 12. The top cover 15 and the gear cavity 16 facilitate the opening of the top cover 15 to add materials into the stirring chamber 11 for stirring. The gear cavity 16 is used to protect each gear and to provide a mounting base for the drive motor 24.

[0032] The mixing component 1 also includes a drive motor 24, which is fixedly mounted on the top of the gear cavity 16. The drive motor 24 facilitates the provision of power to drive the stirring shaft 22 and the spiral scraper 21 to rotate.

[0033] The drive motor 24 has a worm gear 25 fixedly installed at its output end. The worm gear 25 is meshed with a worm wheel 26, which is fixedly connected to the stirring shaft 22. The worm wheel 26 facilitates the operation of the drive motor 24 to make the worm gear 25 drive the worm wheel 26 to rotate, thereby controlling the rotation of the stirring shaft 22.

[0034] The stirring shaft 22 is equipped with a worm gear 26 at one end, and a drive gear 27 is fixedly installed thereon. The drive gear 27 is meshed with a first transmission gear 28. The setting of the drive gear 27 facilitates the rotation of the stirring shaft 22, which in turn drives the first transmission gear 28 to rotate in the opposite direction.

[0035] Among them, a second transmission gear 29 is fixedly installed on the middle of one side of the first transmission gear 28, and a third transmission gear 210 is meshed with the second transmission gear 29. Both the first transmission gear 28 and the third transmission gear 210 are rotatably connected to the inside of the gear cavity 16. The setting of the second transmission gear 29 facilitates the reverse rotation of the first transmission gear 28 to drive the third transmission gear 210 to rotate in the forward direction.

[0036] The third transmission gear 210 is meshed with a driven gear 211, which is fixedly connected to the spiral scraper 21. The driven gear 211 facilitates the forward rotation of the third transmission gear 210 to drive the driven gear 211 to rotate in the opposite direction, thereby controlling the spiral scraper 21 to rotate coaxially and in opposite directions with the stirring shaft 22. It also has a deceleration effect, allowing the spiral scraper 21 to rotate at a slower speed, thus outputting greater torque to scrape the bottom inside the stirring chamber 11. Furthermore, it can reduce the wear rate of the spiral scraper 21 and help improve its service life.

[0037] Specifically, the working principle of this steel slag asphalt pavement mixing device is as follows: During use, the mixing chamber 11 provides the main mixing space to accommodate the mixing component 2 and the steel slag asphalt, facilitating mixing by the mixing component 2. The insulation sleeve 12 and electric heating wire provide a heat source to heat the inside of the mixing chamber 11, maintaining the fluidity of the steel slag asphalt. The insulation sleeve 12 provides insulation to the outside of the mixing chamber 11, reducing heat loss and preventing uneven temperature distribution. The top cover 15 and gear cavity 16 facilitate opening the top cover 15 to add materials into the mixing chamber 11. The material is stirred. The gear cavity 16 protects the gears and provides a mounting base for the drive motor 24. The spiral scraper 21 allows it to rotate inside the stirring chamber 11, stirring the steel slag asphalt and continuously scraping the bottom steel slag to suspend it and prevent sedimentation and stratification. The stirring shaft 22 provides a mounting base for the stirring paddle 23, allowing it to rotate inside the spiral scraper 21. The drive motor 24 provides power to drive the stirring shaft 22 and spiral scraper 21. The worm gear 26 facilitates the operation of the drive motor 24. The worm gear 25 drives the worm wheel 26 to rotate, thereby controlling the rotation of the stirring shaft 22. The drive gear 27 facilitates the rotation of the stirring shaft 22, causing the drive gear 27 to drive the first transmission gear 28 to rotate in the opposite direction. The second transmission gear 29 facilitates the reverse rotation of the first transmission gear 28, which in turn drives the third transmission gear 210 to rotate in the forward direction. The driven gear 211 facilitates the forward rotation of the third transmission gear 210, which in turn drives the driven gear 211 to rotate in the opposite direction. This achieves the control of the spiral scraper 21 and the stirring shaft 22 to rotate coaxially but in opposite directions, and also provides a deceleration effect, allowing the spiral scraper 21 to rotate more slowly. The mixing shaft 22 rotates at a speed that outputs greater torque to scrape the bottom inside the mixing chamber 11, reducing the wear rate of the spiral scraper 21 and improving its service life. The mixing paddle 23 and the spiral scraper 21 have the same spiral twisting direction, which facilitates the rotation of the mixing shaft 22 to drive the mixing paddle 23 to rotate in the middle of the mixing chamber 11 for mixing. The mixing paddle 23 and the spiral scraper 21 rotate coaxially but in opposite directions, causing the steel slag asphalt inside the mixing chamber 11 to form a counter-current vortex, enhancing mixing and preventing stratification. The discharge port 13 facilitates the discharge of the evenly mixed steel slag asphalt, and the control valve 14 controls the opening and closing of the discharge port 13.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
